Question

According to the fundamental theorem of algebra, how many zeros does the function f(x)=4x^3-x^2-2x+1 have?

Answer 1

Since the maximum exponent of x is 3, there should be three roots.
Unless you have a root squared and multiplyed by a different root, you will only have two roots since two are the same.
Also, if all three roots are the same, you only have one root.
